Within the international race to decarbonize, hydrogen stands out as some of the promising clear fuels. However regardless of its potential to energy industries and transportation with out emitting carbon, producing hydrogen sustainably in a water electrolyzer has been restricted by the excessive price and shortage of 1 important ingredient: iridium.
Now, a workforce of researchers at Rice College has developed a brand new catalyst that dramatically reduces the quantity of iridium wanted in proton alternate membrane (PEM) water electrolyzers, a key know-how for producing inexperienced hydrogen from water.
Their innovation—an iridium-stabilized ruthenium oxide catalyst that makes use of simply one-sixth as a lot iridium as standard techniques—maintains industrial-level efficiency for greater than 1,500 hours of steady operation.
The analysis was revealed in Nature Nanotechnology.
“This is a significant step toward making green hydrogen more accessible and scalable,” mentioned Haotian Wang, affiliate professor of chemical and biomolecular engineering at Rice. “By reducing iridium use by over 80%, we’re addressing one of the biggest economic and supply chain bottlenecks in the hydrogen economy.”
Present PEM electrolyzers rely closely on iridium as a result of it is without doubt one of the few…
